Product Description

Down-hole Motor
Specifications
1. a kind of downhole drill tool driven by mud.
2.Type:LZ series
down hole motor
 
As mud fluid from the mud pump enters the motor via the by-pass valve, a certain pressure difference is formed at the inlet and outlet of the motor, pushing the rotor to rotate. Torque and rotate speed are transferred via the cardan shaft and the driving shaft to the bit.
Performance of the down-hole drill motor depends mainly on performance parameters of the 
screw motor.
